(CNN) As athletes and tourists arrive in South Korea ahead of the 2018 Winter Olympic Games in Pyeongchang , health officials on the Korean Peninsula are battling two strains of influenza. Flu outbreaks in both North and South Korea have raised concerns for those traveling to the region. By comparison, South Korea reported 1,250 confirmed cases of both A and B influenza virus to the WHO between December 4 and January 28. "Influenza may only be starting up naturally in South Korea, but it is possible that some people traveling from North Korea could augment that by bringing the virus with them." During the Olympic Games, athletes, trainers and sporting officials typically reside in housing venues referred to as an Olympic Village.
